CoolGear USB2-4COM-SI-M Manual

USB2-4COM-SI-M 2.0 to 4 Port RS-232 Serial Adapter Optical Isolated Manual
The USB2-4COM-SI-M USB Serial Adapter is designed to make serial port expansion quick
and simple. Connecting to a USB port on your computer or USB hub,
the USB Serial Adapter instantly adds serial communication port to
your system. By taking advantage of the USB bus, the USB Serial
Adapter makes it easier than ever to add serial port and serial device
to your system with easy plug-and-play and hot plug features.
Adapting the new technology, the serial port expansion now takes the
new bus with easy and convenient connectivity.
Plugging the USB Serial Adapter to the USB port, the adapter is
automatically detected and installed. There are no IRQ & COM port
conflicts, since the port doesn't require any additional IRQ, DMA,
memory as resources on the system. The RS-232 port functions as native Windows COM port, and it is compatible with
Windows serial communication applications. Each port is individually configurable.
The USB Serial Adapter provides instant connectivity to RS-232 communication device for factory automation
equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminal and serial
communication in harsh environment. The USB to Serial Adapter is suitable for remote access, retail and industrial
application, data collection and other applications requiring high speed RS-232 communication ports.
Optical Isolation and Surge Protection
Optical isolation and surge protection is available to USB2-4COM-SI-M. Each serial port is individually optically isolated
with 2000 volt DC optical isolation. The optical isolation protects your computer from spikes and surges, by converting
the electrical pulse into an optical signal and then changing it back into an electrical pulse. Your computer is well
protected, since the surges and spikes cannot cross the optical link. Each serial port is individually protected by surge
protector to withstand electrostatic discharge and power surges up to 25KV ESD. Surge suppression on all signals
prevent from damages caused by lightning or high voltage.
